Created for feedback and discussion about vlc-rpi announced here.

Hi,

both vlc and vlc-rpi can't sem to play m3u8 streams. Tried on a (armv8) raspberrypi 4 and on a (armv7h) rasp 3b.
I'm trying to play this: https://wzstreaming.rai.it/TVlive/liveS ... 33699.m3u8

and vlc fails with

$this->bbcode_second_pass_code('', '
adaptive demux: Changing stream format Unknown -> TS
main demux debug: creating demux: access='' demux='ts' location='' file='(null)'
main demux debug: looking for demux module matching "ts": 51 candidates
ain demux debug: no demux modules matched
')

Vlc on (x86_64) Arch works fine

$this->bbcode_second_pass_code('', 'adaptive demux: Changing stream format Unknown -> TS
main demux debug: creating demux: access='' demux='ts' location='' file='(null)'
main demux debug: looking for demux module matching "ts": 55 candidates
ts demux debug: Standard set to Auto
main demux debug: using demux module "ts"
ts demux debug: first packet for pid=0 cc=0x4
ts demux debug: PATCallBack called
')

mpv plays the stream fine on the raspberry pi, so I guess it's not a ffmpeg issue

I need a sample file to try to reproduce. The one you linked doesn't offer any content as far as I can tell.

EDIT: this works on my RPi4

$this->bbcode_second_pass_code('', '% cvlc https://devstreaming-cdn.apple.com/videos/streaming/examples/img_bipbop_adv_example_fmp4/master.m3u8')

Hi, your stream is muxed in MP4 format, I can open it fine too. I get

$this->bbcode_second_pass_code('', 'adaptive demux: Changing stream format Unknown -> MP4')

The one I posted is TS. It does offer content, try opening it in a different player. This one is another example: mpv opens it, vlc fails

$this->bbcode_second_pass_code('', 'cvlc https://d15umi5iaezxgx.cloudfront.net/LA7/CLN/HLS-B/Live_1280x720_.m3u8')

$this->bbcode_second_pass_code('', ' adaptive demux: Changing stream format Unknown -> TS
adaptive demux error: Failed to create demuxer (nil) TS
')

The first one you posted does not load in vlc on Arch Linux x86_64 for me.
$this->bbcode_second_pass_code('', '% cvlc https://wzstreaming.rai.it/TVlive/liveStream/chunklist_w810233699.m3u8

Also does not work on vlc-rpi on RPi4.

It does work with mpv on Arch Linux x86_64. I suspect you uncovered a bug with either vlc or with Arch's package of vlc. Recommend you open a bug report against vlc on Arch Linux's tracker but do not reference ArchARM. I assume you have an Arch Linux x86_64 box, no?

EDIT: I CAN in fact get your original stream to work with vlc but only when I use my modified PKGBUILD I use to strip out unneeded options (for my use case). You can find my PKGBUILD here. I opened a bug report, FS#76535.

Strange. I can play it fine with the stock x86_64 vlc, see log

See the bug report I referenced above: you're missing a dependency.

Thank you very much!
